Qualitative Modeling of the Quasiparticle Green’s Function in Cuprates Based on ARPES Data — •Dmytro Inosov¹, Sergey Borisenko¹, Alexander Kordyuk^1,2, Volodymir Zabolotnyy¹, Jochen Geck¹, Andreas Koitzsch¹, Jeorg Fink¹, Martin Knupfer¹, and Bernd Büchner¹ — ¹Leibnitz-Institut für Festkörper- und Werkstofforschung, IFW-Dresden, P.O.Box 270116, D-01171 Dresden, Germany — ²Institute of Metal Physics of National Academy of Sciences of Ukraine, 03142 Kyiv, Ukraine

ARPES data provides a detailed view of the renormalized band structure in cuprates and, consequently, is a key to the self-energy and the quasiparticle Green’s function. However, due to the matrix elements and experimental specifics, comparison with the results provided by different experimental techniques is not straightforward. A model which would allow such a comparison with STM, INS, and RS data is proposed.
